I do not need a solution (just sharing information)
Service Pack 2 for Symantec System Recovery (SSR) 2013 will be available soon and, amongst other things, will bring support for Windows 8.1 and Windows Server 2012 R2.
I cannot provide an exact date for the release of SP2 at this stage but this thread will be updated with details (release notes etc) when SP2 is available.
Please let me know if you have any questions.
